Reaching 18M Ohm Water Quality

Deionized water (“DI water”) is generated through the process of deionization, whereby residual total dissolved solids (TDS) are removed from water through a resin-based ion-exchange process. In the deionization process, both positively charged ions (cations) and negatively charged ions (anions) are removed from water in exchange for hydrogen and hydroxide ions, which unite to form pure water molecules.

Service deionization (SDI)

Pure Flow offers DI resin exchange services to assist our customers in production of DI water. Service deionization (SDI) provides a safe, convenient & cost-effective supply of high purity DI water.

Our team operates multiple ion exchange resin regeneration plants in the Northeast US, allowing extreme quality control for customer-specific resin regeneration requirements.

Electrodeionization (EDI)

For certain applications, electrodeionization (EDI) can be an appropriate substitute for mixed bed ion exchange vessels (SDI). EDI technology employs ion exchange membranes, electricity, and resins in a deionization process that separates dissolved ions from water.

EDI is often utilized in a polishing stage following reverse osmosis (RO). EDI is commonly encountered in pharmaceutical, electronics, and power generation applications.
